Examples for Chapter 3 - RESTful Java with JAX-RS 2.0 - page 267

The output of the build should end with BUILD SUCCESS .

Examining the Source Code

The server-side source code is exactly as posted in Chapter 3 . The guts of the client code are
the same as in Chapter 3 , but the client code is structured as a JUnit class. JUnit is an open
source Java library for defining unit tests. Maven automatically knows how to find JUnit-en-
abled test code and run it with the build. It scans the classes within the src/test/java directory,
looking for classes that have methods annotated with @org.junit.Test . This example has
only one: com.restfully.shop.test.CustomerResourceTest . Let's go over the code for
it that is different from the topic:

src/test/java/com/restfully/shop/test/CustomerResourceTest.java

package package com . restfully . shop . test ;

import import org.junit.Test org.junit.Test ;

import import javax.ws.rs.client.Client javax.ws.rs.client.Client ;

import import javax.ws.rs.client.ClientBuilder javax.ws.rs.client.ClientBuilder ;

import import javax.ws.rs.client.Entity javax.ws.rs.client.Entity ;

import import javax.ws.rs.core.Response javax.ws.rs.core.Response ;

public

public class class CustomerResourceTest CustomerResourceTest

{

@Test
public public void void testCustomerResource () throws throws Exception {

Our test class has only one method: testCustomerResource() . It is annotated with @Test .
This tells Maven that this method is a JUnit test. The code for this method is exactly the
same as the client code in Chapter 3 . When you run the build, Maven will execute the code
within this method to run the example.
That's it! The rest of the examples in this topic have the same Maven structure as ex03_1 and
are tested using JUnit.
